Hello Saguaros,
I did an override, adding the com_virtuemart of Quark to the Hotel folder. Is it an old code? Do you have newer one? Both templates have been recently purchased and I would they were current.
Actually the error isn't active anymore, but the page is completely broken.
The language switch too, for instance, has changed from the previous view. The Language switch was correctly working before.
What other changes you have done, besides renaming the category/default.php?
Thanks
Maurizio
